Fair question!
White folk generally don't listen to Black people about their experiences. And when they do listen, they often don't believe. And when they do listen and believe, they often assume that them thinking about it for 5 or 10 minutes will yield a better solution than proposals from people that have been thinking about it for 5 or 10 years.
And in terms of queer... Mastodon never worked great for queer people in general. Because it never worked great for Black queer people.🤷🏿♂️
